Menu > Admin/manager > System setup > Global lists > To-do status
NOTE: This list is blank by default. The above is an example of how one might set this up.
Status - This labels the to-do status so users know its status.
Color - Can affect how the To Do Board visually shows the To Dos.
Mark as completed - Multiple statuses can have this checked. For example, you might have 'Fixed' and 'Canceled' as status labels, yet both can mark the to-do as 'complete'.
Default - Only one status can be the default used for all new to-dos.
